Abstract
The classical endogenous cannabinoid (CB) system is composed of the endocannabinoid signalling molecules, 2-arachidonoyl glycerol (2-AG) and anandamide (AEA) and their G-protein coupled receptors (GPCR), CB1 and CB2 which together constitutes the endocannabinoid system (ECS). However, putative, novel lipid-sensing CB receptors have recently been identified, including the orphan GPR55 and GPR18 receptors that are regulated by cannabinoid-like molecules and interact with CB system. CB receptors and associated orphan GPCRs are expressed at high levels in the immune and/or central nervous systems (CNS) and regulate a number of neurophysiological processes, including key events involved in neuroinflammation. As such, these receptors have been identified as emerging therapeutic targets for a number of brain disorders in which neuroinflammation is a key feature, including multiple sclerosis (MS) and Alzheimer’s disease (AD). This review will consider the role of the wider cannabinoid receptor superfamily in mediating immune function with a focus on the immune processes that contribute to neuroinflammatory conditions.

New drug therapy for eye diseases
Eyesight is one of the most critical senses, accounting for over 80% of our perceptions. Our quality of life might be significantly affected by eye disease, including glaucoma, diabetic retinopathy, dry eye, etc. Although the development of microinvasive ocular surgery reduces surgical complications and improves overall outcomes, medication therapy is ...read more
Therapeutic Chemical and RNA Design with Artificial Intelligence
Computer-Aided Drug Design (CADD) has emerged as a fundamental component of modern drug discovery. Molecular docking facilitates virtual screening on a large scale through structural simulations. However, traditional CADD approaches face significant limitations, as they can only screen known compounds from existing libraries. PubChem, as the most widely used chemical ...read more
